FineFT: Efficient Risk-Aware Reinforcement Learning for Futures Trading

FineFT introduces a three‑stage ensemble reinforcement‑learning framework that tackles high‑leverage reward volatility and missing ability‑boundary awareness in crypto futures trading by using selective TD‑error updates, VAE‑based market‑state boundary detection, and a risk‑aware routing mechanism, ultimately outperforming twelve baselines on six financial metrics while cutting risk by over 40%.

AI‑Trader: Real‑time Benchmark for Autonomous LLM Agents in Financial Markets

The AI‑Trader benchmark evaluates large language model agents in fully autonomous, real‑time US stock, Chinese A‑share, and cryptocurrency markets, revealing that general intelligence alone does not guarantee profitable trading, while robust risk‑control mechanisms drive cross‑market stability and excess returns.

Quantum‑Enhanced A3C² Leverages Time‑Series Dynamic Clustering for Adaptive ETF Stock Picking

Traditional ETF selection and plain A3C reinforcement learning struggle with high‑dimensional features and static clustering, so the authors propose Q‑A3C², which embeds variational quantum circuits and time‑series dynamic clustering into the A3C framework, achieving a 17.09% cumulative return versus a 7.09% benchmark on S&P 500 components.

Paper Review: TradeTrap – Evaluating the Reliability and Faithfulness of LLM‑Based Trading Agents

The article introduces TradeTrap, a unified framework that systematically stress‑tests large‑language‑model‑based autonomous trading agents by injecting component‑level perturbations—such as data falsification, prompt injection, and state tampering—into a historical US‑stock back‑test, revealing how small disturbances can cascade into extreme risk exposure, portfolio drawdown, and performance collapse.
